WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 571,475, dated November17, 1896. Application filed November 11,1895. Serial No. 568,622. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHNSON MAITLAND GROVER, publisher, residing atToronto, in the county of York, Province of Ontario, Oanada, haveinvented certain new and useful Improvements in l/Vashing-lvlachines, ofwhich the following is a specification.

My invention relates to washing-machines, and its objects are to producean effectual washer which can be easily taken apart, is of simpleconstruction and operation, is adjustable to vessels of different sizesand capable of receiving without alteration articles to be washed ofvarying thickness, and which is productive of a certain new and usefulaction in the operation of washing, whereby a thorough cleansing of thearticles to be washed is accomplished.

To these ends my invention consists of a washing-machine having an uppercorrugated roller carried and adapted to be turned by a crankn arm andbelow lsaid upper roller a rocker having secured thereto twoindependently rotatable compressing rollers, said rocker and upperroller supported at each end of the apparatus in tubular standards fixedto a base of wood or other material, means Within the tubular standardsto keep theupper roller and rocker normally in contact, while permittingthem to separate, and means to adj ustably attach the machine to awashing vessel, all as more fully hereinafter described and particularlyclaimed.

My invention is illustrated in the accoinpanying drawings, in which-Figure 1 is a front view in elevation, showing brackets for attachment;Fig. 2, a central longitudinal section; Fig. 3, a transverse sectionalview through roller and rocker; Figs. a and 5, details showing thespring-retaining and roller-supporting rod, and Figs. (i and 7 detailsof locking device; Fig. 8, a rear end view of rocker-plate, and Figs. 9and lO details of brackets to support machine.

Referring to the drawings, A is the upper roller, supported and adaptedto be turned by the crank-arm B, which is provided with a crank-handle.

The roller A may be of Wood, vulcanized `the motion of the latter.

rubber, or like material, and is provided on its surface withlongitudinal corrugations or ridges.

The crank arm or shaft B is supported in slots c of tubular standards CO', which standards are fixed to the base D of the machine by screwbolts and nuts or other suitable means.

Passing through each of the tubularstandards is a rod E, having a hangedtop or cap e, which rests on the top of the standard, the other end ofthe rod being provided with lugs e', which engage with a cross-slottedlockingwasher F to lock the rod in place. Near its upper end the rod Eis provided with a vertical slot e2, in which the shaft of the upperrollerA is held and turns. A horizontal opening e3 in this slot permitsthe shaft and roller to be removed from the machine when the rod isunlocked and raised.

G is a rocker having a slightly-concave upper surface J and a convexunder surface and placed below and in contact with the corrugated rollerand having at each end a forked arm or arms g', which enter the tubularstand ard and loosely embrace the rod E. A strong coiled springHsupports these arms and also serves other purposes, as hereinafterdescribed. The rocker G is provided with two independently rotatablerollers K, one on each side of the plain surface portion J of therocker. These rollers are in contact with the large corrugated rollerand are controlled by The plain surface J, extending between thecompressing-rollers K, constitutes a rubbing-board.

The coiled spring H, surrounding the rodV E at its lower end, bears uponthe lockingwasher F and presses the same downward. This pressure pullsthe rod E downward, and consequently the shaft of the upper roller heldin the slot e2. The iianged cap e of the rod prevents the latter frombeing drawn through the standard by the pressure of the spring. At itsupper end the spring exerts a strong upward pressure against the forkedarms of the rocker G, and thus keeps the rocker pressed closely againstthe corrugated roller. It will thus be seen that both at the lower andupper ends of the spring the action of said spring tends to keep theupper roller and the rocker in close contact.

The tubular standards are identical in construction, except in respectto their means of attachment to the tub or other washing vessel. Thestandard C is provided near its lower end with two cylindricalprojections or pins c2, one. above the other, adapted to enter the holesfm m in the bracket M, (shown in Fig. 10,) which bracket is adapted tobe fastened to the inner side of the vessel by screws or other suitablemeans. The standard C has at its upper end a horizontal slotted arm c3,carrying a threaded bolt c4, having a thumbnut. At its lower end thisbolt has a projection O, adapted to enter the slot or keyhole p in thebracket P, which is secured to the tub on the opposite side from that onwhich bracket M is placed by screws through screwholes p2. The bolt c4can be moved along. the arm c3 in the slot c5 therein and adjusted tovessels of any size.

In the operation of washing, after the apparatus has been secured to theinterior of the washing vessel by the means above described, the clothesor other articles to be washed, after having been well soaked, areplaced between the upper roller and the rocker and the former turned bythe crankhandle. In revolving the corrugations of the upper roller,pressing against the' material being washed, cause the lower rollers toturn, permitting the articles to pass through. By the peculiarconstruction of the rocker provided with the compressing-rolls and arubbing-board and the upper roller provided with corrugations theclothes are subjected to a squeezing and wringing action, and by meansof the open forked arms of the rocker, which permit the rocker-plate torock on the springs Il, a rubbing action is also obtained,

by which a thorough cleansing of the articles iseiected. Owing to thespring action by which the compressing power is obtained the roller androcker will yield and separate or approach each other to accommodatearticles of different thickness and buttons on the clothing will beallowed to pass through without being torn off or destroyed.

From the foregoing description of the parts of the machine it will beseen that the apparatus can be easily and quickly taken apart or puttogether.

Having thus described my invention, what I claim isl. In awashing-machine, in combination with the roller-shaft, the tubularstandard, slots in said standard to receive the shaft, a detachablesupporting-rod Within said standard, said rod having a vertical slot toreceive said roller-shaft, and an opening in said slot, whereby theroller-shaft may be removed when the rod is detached, substantially asdescribed.

2. In combination with the upper roller and the rocker, the tubularstandard, open at each end, the slotted supporting-rod within saidstandard, said rod provided with a iianged top, a locking-washer, andmeans on the lower end of said rod to engage said washer, said rockerprovided with supporting-arms entering the standard, and a spring.confined be tweenl said arms and said washer, substan-l tially as andfor the purpose described.

3. In a washing-machine, in combination with a suitable roller, endstandards for supporting said roller, each of said standards providedwith a rod slotted to receive the axis of said roller, said rod providedwith a iianged cap at its upper end and lugs at its lower end, and saidstandard provided with a cross-slotted washer to receive the lower endof the rod, substantially as and for the purpose dc- J (HINSONlllAlTLAND GROVER.
